Hello everyone. I'm new here so I thot I would start a thread on a subject that is near and dear to me. A little introduction about myself. I grew up in central Maine, started cutting pulp for my dad a few months before my 13th birthday in 1973. Running McCullough Super 2-10 Automatic saws. Worked my way thru school farm and skidded logging there. Went in the service to get to Alaska . Got here in 78 and by and large haven't left since. Got out of the service when my 4 years was up and already had a pre commercial tree thinning sub contract on Revilla Is in Southeast Alaska. Then got into tower logging and after 6 years I got to break in cutting timber. Cut till our timber industry went belly up then got into banging nails , highway const , drilling , mining, running iron and truck driving . Which is what I currently do for a living. Since the invention of the power chain saw 2 things have remained constant. The bar MUST be straight and true . The chain MUST be sharp and properly jointed. It matters very little what engine pulls the chain around the bar. What matters most is that the chain will cut well and the bar keeps the chain running straight.
